Create New ZIP Archive
This section provides a tutorial example on how to create a new ZIP archive and add files into the archive using the ZipArchive class.
The best way to create a new ZIP archive is to use the "ZipArchive::CREATE" flag in the $zip->open() method. For example, the following code will create a new empty ZIP archive, if '/tmp/test.zip' does not exist. If '/tmp/test.zip' exists, it will be open to add new entries or extract entries. It fails only if '/tmp/test.zip' exists and is not a ZIP file.
$zip = new ZipArchive; $zip->open('/tmp/test.zip',ZipArchive::CREATE);
Here is an example script that create a new ZIP archive and adds some files into the archive.
<?php # zip-create-new.php #- Copyright 2009 (c) HerongYang.com. All Rights Reserved. $zip = new ZipArchive; echo "Creating test.zip:\n"; $rc = $zip->open('/tmp/test.zip',ZipArchive::CREATE); if ($rc === TRUE) { echo " test.zip opened\n"; $file = 'dot.gif'; if ($zip->addFile($file) === TRUE) { echo " $file added\n"; } else { echo " Failed to add $file.\n"; } $file = 'zip-create-new.php'; if ($zip->addFile($file) === TRUE) { echo " $file added\n"; } else { echo " Failed to add $file.\n"; } $file = 'junk.jnk'; if ($zip->addFile($file) === TRUE) { echo " $file added\n"; } else { echo " Failed to add $file.\n"; } $zip->close(); } else { echo " Failed to create test.zip with error: $rc\n"; } ?>
Let's try it:
herong$ php zip-create-new.php Creating test.zip: test.zip opened dot.gif added zip-create-new.php added Failed to add junk.jnk. herong$ unzip -l /tmp/test.zip Archive: /tmp/test.zip Length Date Time Name --------- ---------- ----- ---- 43 03-01-2020 14:15 dot.gif 815 03-01-2020 15:17 zip-create-new.php --------- ------- 858 2 files
